In many countries, lenders are restricted in their access to information about borrowers' past defaults. The authors study this provision in a model of repeated borrowing and lending with moral hazard and adverse selection. They analyze its effects on borrowers' incentives and access to credit,...

We build a New Keynesian model in which heterogeneous workers differ with regard to their employment status due to search and matching frictions in the labor market, their potential labor income, and their amount of savings. We use this laboratory to quantitatively assess who stands to win or...

We study empirically and theoretically the growth of U.S. manufacturing exports from 1987 to 2007. We identify the change in iceberg costs with plant-level data on the intensity of exporting by exporters. Given this change in iceberg costs, we find that a GE model with heterogeneous...

We show the existence of an inherent instability associated with a purely private monetary system due to the role of endogenous debt limits in the creation of private money. Because the bankers' ability to issue liabilities that circulate as a medium of exchange depends on beliefs about future...

We develop an empirical framework for the credit risk analysis of a generic portfolio of revolving credit accounts and apply it to analyze a representative panel data set of credit card accounts from a credit bureau. These data cover the period of the most recent deep recession and provide the...

The large, persistent fluctuations in international trade that cannot be explained in standard models by changes in expenditures and relative prices are often attributed to trade wedges. We show that these trade wedges can reflect the decisions of importers to change their inventory holdings. We...

An important source of inefficiency in long-term debt contracts is the debt dilution problem, wherein a borrower ignores the adverse impact of new borrowing on the market value of outstanding debt and, therefore, borrows too much and defaults too frequently. A commonly proposed remedy to the...

Self regulation encouraged by market discipline constitutes a key component of Basel II's third pillar. But high-risk investment strategies may maximize the expected value of some banks. In these cases, does market discipline encourage risk-taking that undermines bank stability in economic...

We show that the regulation of bank lending practices is necessary for the optimal provision of private liquidity. In an environment in which bankers cannot commit to repay their creditors, we show that neither an unregulated banking system nor narrow banking can provide the socially efficient...

Motivated by the recent experience of the U.S. and the Eurozone, we describe the quantitative properties of a New Keynesian model with a zero lower bound (ZLB) on nominal interest rates, explicitly accounting for the nonlinearities that the bound brings. Besides showing how such a model can be...
